For those of you to lazy to read the article here is the short and sweet version, you have 4 main lifts (bench, squat, overhead press, and dead lift) and you do three sets at different percentages of your max and with different reps depending on what week it is. The first three weeks are your gaining weeks followed by a deload week.

The linked artile goes over a few different 5/3/1 plans (I am doing boring but big) so it is worth the read.

I personaly really like the freedom in ther workout, aside from the 4 big lifts you are free to choose what assistance lifts you want to do so long as you are not putting more importance on these lifts then the big 4.

Admitedly I am only two months into the work out but I have noticed gains in both day to day strength and in muscle definition. I also feel that my explosiveness in judo has increased but that could be me imagining things.

I have stalled a few times on all the lifts so I just follow the program and reset a few cycles back. Like what has already been said I like the simplicity of it and the fact you can do the 4,3 or 2 day a week template depending on your goals and other commitments.

The key to any program is to just stick with it and not program hop to the lastest fad every few months.
